This volume includes twelve studies by international specialists on Aristotle and his commentators. Among the topics treated are Aristotle's political philosophy and metaphysics, the ancient and Byzantine commentators' scholia on Aristotle's logic, philosophy of language and psychology as well as studies of broader scope on developmentalism in ancient philosophy and the importance of studying Late Antiquity.

Ancient dialectic started as an art of refutation and evolved into a science akin to our logic, grammar and linguistics. Scholars of ancient philosophy have traditionally focused on Plato's and Aristotle's dialectic without paying much attention to the diverse conceptions and uses of dialectic presented by philosophers after the classical period. To bridge this gap, this volume aims at a comprehensive understanding of the competing Hellenistic and Imperial definitions of dialectic and their connections with those of the classical period. It starts from the Megaric school of the fourth century BCE and the early Peripatetics, via Epicurus, the Stoics, the Academic sceptics and Cicero, to Sextus Empiricus and Galen in the second century CE. The philosophical foundations and various uses of dialectic are closely analysed and systematically examined together with the numerous objections that were raised against them.

The sixteen essays written in honour of Jonathan Barnes for this volume reflect the impressive scope of his contributions to philosophy. Six are on knowledge, five on logic and metaphysics, five on ethics. The volume ranges widely over ancient philosophy, while also finding room for for two contemporary papers on truth and vagueness. Aristotle is prominent in eight of the essays; Plato, Sextus Empiricus, the Stoics, the Epicureans, and ancient Greek medical writers are also discussed. The contributors include some of the most distinguished scholars of our time.

The volumes of the Symposium Aristotelicum have become essential reference works for the study of Aristotle. In this nineteenth volume, eleven distinguished scholars of ancient philosophy provide a running commentary on the first book of Aristotle's Physics, a central treatise of the Aristotelian corpus that aims at knowledge of the principles of physical change. Along with the general introduction, the ten chapters together comment on the entirety of the Aristotelian text and discuss the philosophical issues that are raised in it in detail. Aristotle is shown to be in dialogue with the divergent doctrines of earlier philosophers, namely with the Eleatics' monism, with Anaxagoras' theory of mixture, and finally with the Platonist dyadism that posits the two principles of Form and the Great and Small. Aristotle uses critical examination of his predecessors' views as the basis for formulating his own theory of the principles of natural things, which are fundamental for the entire Aristotelian study of the natural world. He provides his own solution to the problem of coming-to-be and passing-away by distinguishing between coming in actuality and in potentiality. Comprehensive analysis of Aristotle's doctrines and arguments, as well as critical discussion of rival interpretations, will make this volume a valuable resource for scholars of Aristotle.

Byzantine philosophy is an almost unexplored field. Being regarded either as mere scholars or as primarily religious thinkers, Byzantine philosophers have not been studied on their own philosophical merit. The eleven contributions in this volume, which cover most periods of Byzantine culture from the 4th to the 15th century, for the first time systematically investigate the response of the Byzantines to their inheritance from ancient philosophy to uncover the distinctive character of Byzantine thought.

Stoicism (third century BC to second century AD) is one of the richest and most influential intellectual traditions of antiquity. Leading scholars here contribute new studies of a set of topics which are the focus of current research in this area. They combine careful analytical attention to the original texts with historical sensitivity and philosophical acuity, to provide the basis for a better understanding of Stoic ethics, political theory, logic, and physics. Whereas till recently the study of Hellenistic philosophy has been mainly a historical enterprise, these essays demonstrate that a proper treatment of Stoicism engages us in philosophical questions of considerable current relevance and interest.

The two books of Sextus Empiricus' Against the Physicists have not received much attention in their own right, as sustained and methodical specimens of sceptical philosophy. This volume redresses the balance by offering a series of in-depth studies on them, focusing in particular on their overall argumentative structure and on the various ways in which their formal features relate to their contents, showing how Sextus' procedures vary from one section to the other, and throwing new light on the way he was using his sources. It follows Sextus' own division of these two books into nine successive topics, namely god, cause, wholes and parts, body, place, motion, time, number, coming-to-be and passing-away. These nine chapters are preceded by an introduction which discusses a number of general features of Sextus' scepticism and links the conclusions of this volume to some recent discussions on the scope of ancient scepticism.

Byzantine philosophy is an almost unexplored field. Being regarded either as mere scholars or as primarily religious thinkers, Byzantine philosophers, for the most part, have not been studied on their own philosophical merit, and their works have hardly been scrutinized as works of philosophy. Thus, although distinguished scholars in the past have tried to reconstruct the intellectual life of the Byzantine period, there is no question that we still lack even the beginnings of a systematic understanding of the philosophy of the Byzantines. Byzantine Philosophy and its Ancient Sources is conceived as a concerted attempt in this direction. It examines the attitude the Byzantines took towards the ancient philosophical tradition and the specific ancient sources which they relied upon to form their theories. But did the Byzantines merely copy ancient philosophers or interpret them the way they already had been interpreted in late antiquity? Does Byzantine philosophy as a whole lack a distinctive character which differentiates it from the previous periods in the history of philosophy? Eleven scholars, representing different disciplines from philosophy and history to classics and medieval studies, approach these questions by thoroughly investigating particular topics which give us some insight as to the directions in which we should look for possible answers. These topics range, in modern terms, from philosophy of language, theory of knowledge, and logic, to political philosophy, ethics, natural philosophy, and metaphysics. The philosophers whose works our contributors study belong to all periods from the beginnings of Byzantine culture in the fourth century to the demise of the Byzantine Empire in the fifteenth century.

The Historiography of Philosophy is the text, virtually unchanged, of the Nellie Wallace lectures, which Michael Frede gave in Oxford in 1989-90. In these lectures, Frede is largely concerned with how the history of philosophy has been studied and how it should be studied, that is, how we ought to conceive of and explain what historians of philosophy have been doing and should be doing. He distinguishes three systematical approaches to the history of philosophy, which run under the same heading 'history of philosophy' and deal with the same material, but they are distinct enterprises: Philosophical Doxography, Philosophical History of Philosophy, and Historical History of Philosophy. All three enterprises are considered by him as perfectly legitimate, but he clearly gives priority to the historical history of philosophy, since the other two ultimately have to rely on its findings; for it is only a historical discipline that can determine which position a philosopher of the past, as a matter of historical fact, took and for which reasons he did, in fact, take it. Frede starts his lectures by showing how the historical history of philosophy differs from the two philosophical studies of the history of philosophy; he then examines the historical discipline in more detail, and finally looks into the consequences of its practice. This volume also contains three previously published articles by Frede on the same topic, a preface by Katerina Ierodiakonou that places Frede's lectures in context, and a postface by Jonathan Barnes that discusses and criticizes Frede's views.

Alexander of Aphrodisias, who flourished c. 200AD, was the leading Peripatetic philosopher of his age. Most of his philosophical energies were spent in commenting upon Aristotle: his commentary on the Prior Analytics remains one of the most thorough and helpful guides to this difficult work; in addition, the commentary preserves invaluable information about various aspects of Stoic logic, and it also presents a picture of categorical syllogistic at a turning point in its historical development. This volume contains a translation of the first third of the commentary - the part dealing with non-modal syllogistic. The translation is preceded by a substantial introduction which discusses Alexander's place in the commentatorial tradition and his use of logical terminology. The book is completed by a translation of the pertinent part of the Prior Analytics, a summary account of categorical syllogistic, and a set of indexes.
